jquery - Javascript - check for variable -

here nooby question answer searched way long while not finding anything. i'm not used javascript other programming languages so, how work if want checked for?

here code:

var test = 0;  $( ".test_div" ).click(function() {     test = 1; }); 

now if want check if variable 1, constantly, do? tried didn't work:

if (test == 1) { } 

thanks!

you searching done in interval

following you:

var test = 0; var interval;  function check_test() {     if( test == 1 ){         clearinterval( interval );         console.log( "test 1 now!" );     } }  interval = window.setinterval( check_test, 1000 ); 

the 1000 in milliseconds, 1000 ms = 1 second. call check_test() every 1sec.

you window.settimeout in simmiliar way, 1 time. call inside function again , if want stop it, stop calling it.
